The largest study to date on the early detection of colorectal cancer offers benchmark data for what could be expected from large-scale use of flexible sigmoidoscopy as a screening tool for colorectal cancer. The report, published in the July 6 issue of the Journal of the National Cancer Institute (JNCI), is part of the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, a randomized, community-based longitudinal study evaluating the effectiveness of cancer screening tests on site-specific mortality.
"In our opinion, we now have published important and valuable baseline data on the use of flexible sigmoidoscopy within a large and randomized group of participants," said Joel Weissfeld, M.D., M.P.H, lead author of the study and associate professor of epidemiology, University of Pittsburgh Graduate School of Public Health. "The findings reveal trends and patterns by gender and age that one may expect to see in a flexible sigmoidoscopy intervention targeting the general U.S. population," added Dr. Weissfeld, who also is co-leader of the cancer epidemiology, prevention and control program at the University of Pittsburgh Cancer Institute.
During flexible sigmoidoscopy (FSG), a doctor uses a lighted scope to examine the inside of the large intestine from the rectum through the descending colon, where most colon polyps develop.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
